We have at least 4... maybe 6 or 7... of the Republican candidates (NOT including Trump) whose primary basis for decision making is rooted in fundamental Christianity. You can imagine what would happen to the 1st Amendment if one of them were elected and appointed several SCOTUS members.

It's not that all Republicans are like that, but many Republicans will shrug at shredding of the 1st Amendment if they also get guns and protection for corporations and strict immigration policies also. (and several other things)
